Patent JP-S5977208-A (JP)
Title: Combustion method
Inventor: MORITA SHIGEKI
IPC: F23C5/08
Filed: 1982-10-25
Abstract: PURPOSE:To reduce production of NOX without an increase in a unburnt content in combustion gas even during combustion of pulverized coal, by a method wherein, in a combustion method employing a burner device provided with multistage burners and an after-air port located on the downstream side thereof, the air ratio of a burner at each stage increases, on the further downstream side this burner is situated. CONSTITUTION:Air ratios lambda1 of first stage burners 20 are set to 0.15-0.65, air ratios lambda2 of second stage burners 30 to 0.60-0.95, air ratios lambda3 of third stage burners 40 to 0.85-1.20, and combustion is carried out in lambda1<lambda2<lambda3. In which case, combustion temperature in the first stage burners 20 is decreased to relatively low temperature, but since the stagnating time is long, an organic nitrogen oxide in pulverized coal is efficiently gasified. The stagnating time in the second stage burners 30 decreases, but since the air ratio is high, combustion temperature increases, and this permits enough gasification of the organic nitrogen oxide in pulverized coal. Further, similarly, the third stage burners 40 may sufficiently gasify the organic nitrogen oxide. The gasified organic nitrogen oxide is burnt under a reduction atmosphere, resulting in the ability to reduce production of NOX.

Title: Vertical type heat exchanger
Inventor: USHIJIMA SAN
IPC: F28D7/06
Filed: 1980-12-26
Abstract: PURPOSE: To permit the gases in a circulating stream to be vented, by connecting vent pipes respectively to the upper ends of an inlet water chamber and an outer water chamber, opening both the ends of a heat transmitting pipe to be spaced between the outlet end of the heat transmitting pipe and outlet of the outlet water chamber.  
     CONSTITUTION: When the circulating stream 16 pressurised by a pump 17 enters the inlet water chamber 1, since the chamber 1 is large, the flow rate thereof drops temporarily, and major part of the bubbles in the circulating stream 16 would not enter directly the heat transmitting pipe 9 but dwells in the upper part of the chamber 1, and is discharged from a vent piping outlet 10 via the vent pipe 20 to a pressuring tank 19. On the other hand minor part of the bubbles flowed into the heat transmitting pipe 8 is passed together with the circulating stream to the outlet water chamber 2, dwells in the upper part of the chamber without passing through the perforated plate 14 since the distance between the outlet 8b of the heat transmitting pipe 8 and the water chamber outlet 12 is long enough and the bubbles would be bounced on the perforated plate 14, and is discharged from a vent piping outlet 13 via the vent pie 21 to the pressuring tank 19.

Title: Dc brushless motor drive device for compressor
Inventor: TAKEGAWA YORIYUKI
IPC: H02P6/17
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To restrain drive current effectively at the time of synchronous operation for easy matching, by making the accelerating percentage of rotational speed become a primary lag characteristic while the rotational accelerating operation of a magnetic rotator by an acceleration control signal is applying drive voltage whose duty ratio is constant to a drive winding. SOLUTION: An acceleration control signal generating part 48 conducts an acceleration control signal generating program and turns on selected two of transistors U to Z to be conductive. A control signal SS is outputted, which makes the accelerating percentage of a DC brushless motor 10 become a primary lag characteristic during the energizing time by the continuity of the selected transistors. As a result, by keeping applied voltage (duty ratio) constant, it is possible to always supply the electric power appropriate for a synchronous operation to the DC brushless motor 10 and facilitate matching.

Abstract: PROBLEM TO BE SOLVED: To reduce the heat generation and the resistance loss when a pump is operated at high speed by forming one or a plurality of recesses in a dedendum part or a root part, or both of each gear in a gear pump comprising a pair of gears having a plurality of teeth. SOLUTION: In a gear pump, the fluid flowing in a suction port is pressurized and discharged from a discharge port by the rotation opposite to each other of a pair of gears 21, 22 stored in a pump housing. The resistance when the gear pump is operated is generated especially at a part where the gears 21, 22 at a center part of the pump are engaged with each other. A recess 23 is provided in a dedendum part (or a root part) of the gears 21, 22, and when the gears 21, 22 are engaged with each other, the recess 23 plays a role of an interference tank as a release part of the fluid, and the rotation resistance is reduced.
